Figure data for Giant bubbles of Fisher zeros in the quantum XY chain

The data consist of the frequencies shown in Fig. 3b and Fig. 3c, and the 1/\beta_{i} values in the insets of Fig. 4b and Fig. 4c. The other figures are either schematic illustrations or were directly obtained from the analytic form of the partition functions.本数据集包含图3b与图3c展示的频率数据，以及图4b和图4c内嵌子图中的1/β_i数值。其余图表均为示意图，或直接源自配分函数的解析形式。
